AUXILIARY PUMP
In some cases (excessive distance or differences in level) the system
must be implemented with a "loop" supply circuit with an auxiliary
pump, avoiding to connect the burner pump directly to the tank.
In this case, the auxiliary pump can be started when the burner starts
and stopped when it stops.
The electric wiring of the auxiliary pump is made by connecting the coil
(230V) which controls the pump remote control switch in parallel to the
motor-fan remote switch coil.
Always follow the instructions below:
•
The auxiliary pump must be installed as close as possible to the
liquid to be sucked.
•
The head must be suitable for the relative plant.
•
We recommend a flow rate equal at least to that of the burner pump.
•
The connection pipes must be dimensioned based on the flow rate
of the auxiliary pump.
•
Avoid electrically connecting the auxiliary pump directly to the
remote control switch of the burner.
